This happened after the album was released, and although Gary was a good singer, he did not quite appeal to the old Van Halen fans, and somewhat failed to attract new ones. In short, the album he recorded with the band was not successful. Some speculate Gary was fired because of that, while others say that Eddie just has too much of an ego, but the fact remains. I'm not a big Van Halen fan, but I still felt cheated after reading all those wonderful interviews, and then a couple month later hearing about the change in the band lineup.
